What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Unexpected azygos vein injury during thoracoscopic lung resection is rare. Here, we describe a case of azygos vein arch injury caused by an ultrasonic scalpel. The patient underwent segmentectomy for right upper lobe lung cancer. The ultrasonic scalpel was activated while its blade tip was inadvertently grasping the vascular wall of the azygos vein arch during management of bleeding from the pulmonary artery stump, resulting in injury to the azygos vein arch. Because the injury site was temporarily sealed, it was not initially detected. When the right upper lobe was retracted ventrally to dissect the upper lobe bronchus, tension was applied to the injured site of the azygos vein arch, leading to massive haemorrhage. Conversion to thoracotomy was required, and haemostasis was achieved using a fibrin sealant patch. The azygos vein is a low-pressure system; most injuries can be managed with a fibrin sealant patch.
